ACETYLENEI-GAS oENRAro.

SPECIFICATION forming part of Letters Patent No. 650,132, dated Ma 22, 1900.

Application filed February 8, 1900. Serial No. 41549. (No model.)

To all whom it may concern:

Be it known that I, LABAZURE O. MCLANE, a citizen of the United States, residing at Linesville, in the county of Crawford and State of Pennsylvania, have invented certain new and useful Improvements in Acetylene- Gas-Generating Mechanism; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, forming part of this specification. :5 My invention relates to improvements in acetylene-gas-generating mechanism of the type set forth and described in Letters Patent No. 626,437, granted upon my application on June 6, 1899; and this invention consists, substantially, in the improvements hereinafter set forth and explained, and illustrated in the accompanying drawings, inwhich.

Figure 1 is a front view in elevation of my improved acetylene-gas-generating mechan- 2 5 ism. Fig. 2 is a side view in elevation of the same. Fig. 3 is a top or plan view of the same. Fig. 4 is a View of the bottom thereof. Fig. 5 is a vertical section of a portion of the same on the line as w in Figs. 4 and 6. Fig. 6 is a horizontal section of the same on the line y y in Fig. 5. p

In the drawings thus illustrating my invention, A is a tank provided with a bottom A, secured therein some distance from the base 3 5 thereof, so as to leave a space or chamber A between the bottom A and the base of the tank A. In the tank A is a gas-holder B, operating therein in the usual manner. In the center of the tank A there is a vertical escapepipe 0, which passes down through the center of the tank-bottom A, where it connects by means of a T c with a lateral pipe 0, which extends laterally in one direction as a brace under the bottom A and in the opposite di- 4 5 rection to a waste-pipe 0 outside of the tank A, adapted to extend by suitable connections outside of a building in which the mechanism is being operated. Secured to the top of the center of the gas-holder B there is a pipe D, provided with lateral openings (1, which pipe telescopes over the central pipe 0 and prevents the escape of gas from the holder therethrough until the openings 01 01 rise above the Water-line w in the tank A. Under the bottom A of the tank A at one side of the Gentral pipe Q there is a small inclosed tank or chamber E, and passing under the tank-bottom A and entering the top of a small tank E there-is a horizontal pipe F, which leads from the generators G G, and from a T f under the tank-bottom A a pipe H extends up into the gas-holder B, so that the gas passes from the generators G through the pipes F and H .into the gas-holder, while any condensation accumulatin gin said pipe passes into the tank E. Under the tank-bottom A there is another horizontal pipe I, which by means of an elbow iand a vertical pipe I and an elbow and nipple 1" extends into the bottom of the tank E, and from a T i in the pipe I under the tank-bottom A a pipe J extends up into the gas-holder B, and from an elbow t outside of thetank A a pipe I leads to the gas-burners, (not shown,) so that any condensation of the gas passing out through the pipes J, I, and I passes down into the bottom of the tank E. Connected with the bottom of the tankE there is another pipe K, ending in a funnel K outside of the tank A. This pipe K is also connected by pipes K with the waste-pipe C. The object of the pipe K and the funnel K thereon is to maintain a water-level in the tank E approximately at the dotted line c, (see Fig. 5,) which is done by filling the funnel K up to the notch '70 therein, (see Fig. 2,) which is on a level with the dotted line 6 and serves as an overflow when the water tends to rise above the level of the line 6, water be ing supplied to said funnel from time to time to maintain said water-level. 0

The generators G G are of the type described in my prior patents hereinbefore referred to and are connected with the pipe F by means of branch pipes f f, in which are ordinary three-way cocks L L, one branch of 5 which cocks connects with a waste-pipe M, which connects with the waste-pipe O at the side of the tank A. To the stems of the cooks L L are secured upright rods L L, which extend up to a level with the tops g of the gen- I00 nothave free egress therefrom. ,mer patent the th ree-way cock N for control-- 1 ,Nand its connections are the same as that B a laterally-projecting arm 0, which is provided with a T 0, which slides freely up and jectijng rod 0 in which is pivoted or swivele'd, a short lateral rod P, having a hole in the end thereof through which a rod 12, se- "cured to-the plug of the valve N, slides freely, so thatas thevgas-holder 13 moves down and up tjhe rod {It is moved so as to open and close erator-cuvers G G, wherethey are provided with lateral arms Z1, which engage with the tops 9 of the generator-covers G when in the position illustrated in Figs. 1, 2, 3, and 4 and operate to hold the covers G in place, and when in this position the cooks L L are opened ated will'fl'owfreely through'the pipes f,F', and H into the gas-holder; but when the arms Z l are turned into the positions shown in the dotted lines Z Z in Fig. 3 the pipes f f are shutofl, and any gas generated or remaining in the generators Q G will then flow there;

from through the waste-pipesM- and C The object of this arrangement is that the covers G of the generators G cannot be removed without closingthe cocksL, so that there can be no ,Qbackflow. of gas from the gas-holder a'ndisojthat there can be no time that gas can belgeneratedin the generators G when it does In my forlin'g thewatersupply to the generators was operated by lever, chain, andweight mechanism "In this-invention the three-Wajy'cock described in said former patent, with the exception thatlinorder to make the operation of thecock N positive both when opening and closing I -secure to the top of the gas-holder flown on a vertical guide-rod O, secured to theltop of the' tank A. Through the outer end of the armO there is a-doWnwardly-prothe valve or cook N. All of the other features of the water-supply mechanism herein described having been fully shown and described in my patent hereinbefore referred to, further'description thereof is deemed unnecy- V, 1 Fromthei foregoing description the opera tion of the everal parts of the g'a's ge'fierating mechanism herein described is believed to be so obvious that further reference thereto is deemed unnecessary.

Therefore, having described my invention soas. to enable others to construct and operate the same, what I" claim as new, and degas-holder, a waste-pipe extending from the center of the gas-holder down to a lateral wastepipe under the bottom of the gas-holder tank, and a pipeand'funnel connected with thelower part of said small tank and also with said lateral waste-pipe, substantially as and for the purpose set forth;

'In testimony whereof I affix my signature in presence of two witnesses.-
